CHENNAI, 27 MAR: Researchers at the Indian Institute of Technology (IIT), Madras have developed a portable paper-based device that can detect adulterants in milk in just 30 seconds. The technology, which is affordable and easy to use, could revolutionize the testing of milk and other liquids for adulteration.
The device can detect multiple substances commonly used to adulterate milk, including urea, detergents, soap, starch, hydrogen peroxide, sodium-hydrogen-carbonate, and salt. It works by treating filter paper with reagents that react only with specific adulterants. This enables the device to distinguish between milk ingredients and adulterants.
Speaking about the device, Dr. Pallab Sinha Mahapatra, Associate Professor in the Department of Mechanical Engineering at IIT Madras, said, “This 3D paper-based microfluidic device is made up of a top and bottom cover and a sandwich structure middle layer. This 3D design works well for transporting denser liquids at a consistent speed.”
The device could be used to test other liquids for adulteration, including water, fresh juices, and milkshakes. It requires only a milliliter of liquid to test for adulterants.
The adulteration of milk is a growing problem in developing countries like India, Pakistan, China, and Brazil. Adulterants such as water, starch, and detergent are added to milk to increase its volume or improve its appearance. Consumption of adulterated milk can lead to kidney problems, infant death, gastrointestinal complications, diarrhea, and even cancer.
The new technology developed by IIT Madras could help to ensure the safety of milk and other liquids, especially in remote areas of developing countries. The researchers hope that their technology will be adopted by milk producers, regulatory authorities, and consumers, to increase the traceability of tainted milk and prevent the health risks associated with adulteration.
